So, how bad was it? Did the openers outperform Paradise Lost as usual?

yes

it was really bad. Mistakes and fuck ups all over the place by both guitarists. Nick's vocals were truly pathetically bad this time around. They played all the old songs way too fast. Weird thing is PL were really enjoying themselves as were the totally deaf fanboys. This was like a third rate crappy new wave band covering Draconian Times.
I left after they had completed butchering Draconian Times. I left the place feeling cheated and raped.
And what totally baffled me was that a couple of hours after the gig and also during the week after I came across seasoned gig goers who actually dared call this one of the very best live gigs they had ever attended.
It seems like Paradise Lost fanboys are up there with the Anathem and Iron Maiden ones. How the hell is it possible for anyone not to find fault with the pathetic excuse for a live gig?
